' 4DYNAMIC DEAERATOR HEATER Filed July 28. 1939 INVENT OR.

Patented Mar. 18, 1941 UNITED STATES PATENT OFFICE y 6 Claims.

My invention relates to water heaters and more .particularly to a ty-pe of deaerator heater.

It is an object of my invention to provide a deaerator heater whereby Ithe water will be spread over a substantial area and agitated `for a suiiicient time, whereby a dynamic action permits a greater liberation of :air and oxygen or other impurities, which jare a detriment to steam generation.

It isa further object of my invention to provide for heating the water, assisted by a dynamic force within the cham-ber.

In the present instance the water enters an upper chamber and is agitated, at various stages,

a steam spray being applied at each stage whereby an amalgamation-takes place between the water and steam. The water is heated gradually since the steam pressure is applied in the lower stage :and passes `througha steam nozzle and a rotating wheel rigidly secured to the lower disk or shaft, revolving the circular disks within the chamber. The heated water will then pass to a storage space, free from impurities where it is covered with steam to prevent reabsorption of any impurities, and the non-condensed vapor and impurities above the latter :are passed out through the upper chamber into a condenser` whereby the vapor is condensed and the impurities are eX- pelled to the atmosphere.

'I'he principal object of my invention therefore is a lcombined dynamic -deaerator and water heater.

Other objects and novel features will appear as the description of lthe operation and construction of the device progresses.

In the drawing illustrating my preferred ernbodiment of the invention,

Figure 1 is a sectional elevation of the dynamic deaerator and water heater attached to the condenser.

Figure 2 is a sectional view on Athe line 2-2 of Figure 1.

Figure 3 is a sectional view on Ithe line 3-3 of Figure 1. Figure 4 is an enlarged elevational View on the The dynamic deaerator and water heater may be composed of any number of stages and for the `purpose of illustration, I have shown in sectional elevation, three stages I A, 2-A, and 3--A, each of which is composed of `a circular perforated 5 plate, a revolving circular disk and a cylindrical baflle plate. These Stages are identical in structure except that each stage varies in diameter and the side wall of the shell at the last stage is used asa baie. Stage I-A is shown as having a l0 circular plate I3 secured to a sleeve I2 and buttress plates 9, I9 and II, the latter being fixed to the wall of the heater I, as shown in Figure 3.

A revolving perforated circular disk I4, as shown in Figure 4 is secured to an upright shaft 31 and 15 a cylindrical lbaille plate I5 is secured by buttress plates I9 to the shell of the heater. The numeral I6 represents a pipe perforated as lshown in Figure 4, which has a steam feed line I'Iv for supplying steam 'thereto to provide a steam spray in 20 stage I-A.

Stage 2A is of similar construction, shown in Figure 2, and includes -a perforated circular plate 22 secured to a sleeve 2|, the plate being supported by buttress plates I9. A revolving circular 25 disk 24 is provided, perforated as at I4', shown in Figure 4, and secured to shaft 3l. A cylindrical baille plate 23 is secured to radial buttress plates 26, fthe latter being secured to the shell of the heater, and the numeral 25 represents a steam 30 pipe having perforations corresponding to the perforations in pipe I6, and steam inlet pipe II.

Stage 3-A is shown, including -a circular perforated plate 30 secured to a sleeve 29, supported by buttress plates 25, 2T :and 28, as previously de- 35 scribed and a revolving cylindrical disk 3| is secured to the shaft 3l. The disk 3| is perforated to permit discharge of water upon the turbine wheel 33, the latter bein-g secured by bracket-s 32 to disk 3|. Steam is supplied through pipe 33 and nozzle 34 which revolves disks I4, 24 and 3|, which are secured to shaft 31.

In Figure 5, I have shown the turbine wheel 33 and nozzle 34 as a sectional View illustrating the 45 approximate relation of the parts. The numeral 38 represents la shaft bearing secured to the upper face of a circular perforated plate 39, the latter 'being fixed within the casing of the heater and defining a storage space 42.

Numeral 4| represents a suction pipe between the reserve water chamber and suction pump, and pipe 4U represents a water drain.

The numeral represents the feed water inlet discharging on plate 8, shown in Figure 1, where- 55 by the water is spread out a distance through holes onto perforated plate i3 in stage I-A.

It should be noted that the disks I4, 24 and 3| have their peripheral edges inwardly directed and that the perforations i4 are formed circumferentially around the edge thus formed.

What I claim is:

1. A dynamic deaerator and water heater comprising a substantially cylindrical casing having an upper end including an outlet for steam vapor and impurities and a water inlet, said casing having at its lower end a steam inlet and a water outlet, a vertical rotatable shaft within the casing, a. plurality of circular vertically spaced plates fixed to the shaft, said plates having an inwardly turned perforated edge, a perforated plate positioned above each of the first named plates, a perforated spreader plate concentric with the uppermost perforated plate and positioned beneath the water inlet, a steam spray pipe beneath each of the cylindrical plates, a steam turbine wheel connected with the lowermost circular plate, and said steam inlet having a nozzle for discharge of steam against the turbine wheel whereby to rotate the shaft and associated circular plates.

2. The structure of claim 1, in which the circular plates, perforated plates and steam coils progressively increase in diameter in a downward direction.

3. The structure of claim 1, in which certain of the circular plates, perforated plates and coil include a circurnscribing baille plate.

4. A dynamic deaerator and water heater comprising a substantially cylindrical casing having an upper end including an outlet for steam vapor and impurities and a water inlet, said casing having at its lower end a steam inlet and a water inlet, a perforated horizontal partition wall in the casing, a bearing medially of the partition upon its upper side, a shaft rotatably mounted within the bearing, a plurality of circular vertically spaced plates fixed to the shaft, said plates having an inwardly turned perforated edge, a perforated plate positioned above each of the first named plates, each of said last named plates having a bearing for the shaft, a circumscribing baille plate connected to each of the perforated plates, buttress plates connected between the baffle plates and the wall of the casing, a perforated spreader plate concentric with the uppermost perforated plate and positioned beneath the Water inlet, said spreader plate having a bearing complemental to the upper end of the shaft, a steam spray pipe beneath each of the circular plates, a steam turbine wheel connected with the lowermost circular plate, and said steam inlet having nozzles for discharge of steam against the turbine wheel whereby to rotate the shaft and associated plates.

5. The structure of claim 4, in which the circular plates, perforated plates and steam coils, progressively increase in diameter in a downward direction.

6. A dynamic deaerator and water heater comprising a substantially cylindrical casing having an upper end including an outlet for steam vapor and impurities and a water inlet, said casing having at its lower end a steam inlet and a water outlet, a vertical rotatable shaft Within the casing, a plurality of circular vertically spaced plates xed to the shaft, a perforated plate positioned above each of the rst named plates, a perforated spreader plate concentric with the uppermost perforated plate and positioned beneath the water inlet, a steam spray pipe beneath each of the circular plates, a steam turbine wheel connected with the lowermost circular plate, and said steam inlet having a nozzle for discharge of steam against the turbine wheel to rotate the shaft and associated circular plates.
